TontineCoin: Murder-Based Proof-of-Stake
2020 IEEE International Conference on Decentralized Applications and Infrastructures (DAPPS), 2020Proof-of-stake cryptocurrencies avoid many of the computational and environmental costs associated with proof-of-work protocols. However, they must address the nothing-at-stake problem, where a validator might attempt to sign off on competing blocks, with the hopes of earning coins regardless of which block becomes accepted as part of the blockchain ...

EMS: An Extensible and Modular Staking Architecture for Proof-of-Stake Systems
2020 Second International Conference on Blockchain Computing and Applications (BCCA), 2020Staking is an essential component in Proof-of-Stake (PoS) based blockchain systems. While a host of PoS blockchains have staking schemes in place, the implementations of those mechanisms are highly customized to meet the needs of specific blockchains and vary in terms of the offered functionalities.

Securing Proof-of-Stake Blockchain Protocols
2017Proof-of-Stake (PoS) protocols have been actively researched for the past five years. PoS finds direct applicability in open blockchain platforms and has been seen as a strong candidate to replace the largely inefficient Proof of Work mechanism that is currently plugged in most existing open blockchains.

Evolution of Shares in a Proof-of-Stake Cryptocurrency
SSRN Electronic Journal, 2019Do the rich always get richer by investing in a cryptocurrency for which new coins are issued according to a proof-of-stake (PoS) protocol? We answer this question in the negative: Without trading, the investor shares in the cryptocurrency are martingales that converge to a well-defined limiting distribution and, hence, are stable in the long run ...

Minting Mechanism for Proof of Stake Blockchains
2020As an alternative for the computational waste generated by proof-of-work (PoW) blockchains, proof-of-stake (PoS) systems gained a lot of popularity, being adopted by many existing cryptocurrencies. Unfortunately, as we show, PoS-based currencies, where newly minted coins are assigned to the slot leader, inevitably incentivises coin hoarding, as players
